The phenol derivatives of the general formula P-4 (including the phenol compounds of the general formula P-3) can be produced, for example, by hydrolyzing a phenol ester derivative of the general formula: ##STR81## wherein R^(I), E and l are as defined above and R¹³ is C₁ -C₄ alkyl (e.g., methyl, ethyl) or phenyl, in the presence of a base.

As the base which can be used, there can be mentioned, for example, alkali metal hydroxides such as sodium hydroxide and potassium hydroxide; alkaline earth metal hydroxides such as barium hydroxide; and alkali metal carbonates such as potassium carbonate and sodium carbonate.

This reaction is usually effected in a solvent. As the solvent which can be used, there can be mentioned, for example, alcohols such as methanol, ethanol, n-propyl alcohol, ethylene glycol and diethylene glycol; water; or mixtures thereof.

The reaction is usually effected in the range of 0° C. to 200° C. or the boiling point of the solvent used, preferably in the range of 20° C. to 120° C. The reaction time is usually 1 to 50 hours.

The amounts of the reagents to be used in the reaction, although the base can be used in any mole number, are preferably in the ratio of from 1 to 2 moles for the base, to 1 mole of the phenol ester derivative of the general formula P-6.

The phenol ester derivative of the general formula P-6 can be produced, for example, by reacting a phenol ester compound of the general formula: ##STR82## wherein R¹, R¹³, l and L are as defined above, with a compound of the general formula:

    E-H                                                        (P-8)

wherein E is as defined above, in the presence of a base.

This reaction is usually effected in an inert organic solvent. As the solvent which can be used, there can be mentioned, for example, aromatic hydrocarbons such as benzene, toluene, xylene and chlorobenzene; nitriles such as acetonitrile, propionitrile and isobutyronitrile; ketones such as acetone, methyl isobutyl ketone and methyl ethyl ketone; alcohols such as methanol, ethanol and n-propyl alcohol; ethers such as diethyl ether, diisopropyl ether, 1,2-diethoxyethane, tetrahydrofuran and dioxane; polar solvents such as N,N-dimethylformamide, N,N-dimethylacetamide, dimethylsulfoxide, sulforane and hexamethylphosphoric triamide; or mixtures thereof.

As the base which can be used, there can be mentioned, for example, alkali metals such as sodium and potassium; alkali metal hydroxides such as sodium hydroxide and potassium hydroxide; alkali metal carbonates such as sodium carbonate and potassium carbonate; alkali metal hydrides such as sodium hydride; alkali metal alkoxides (e.g., C₁ -C₄ alkoxides such as methoxides and ethoxides) such as sodium ethoxide and sodium methoxide; and organic bases such as pyridine, triethylamine, N,N-dimethyl-aniline and 4-N,N-dimethylaminopyridine.

The reaction is usually effected in the range of 0° C. to 200° C. or the boiling point of the solvent used, preferably in the range of 20° C. to 120° C. The reaction time is usually 1 to 50 hours.
